Question

which subatomic particle has a positive charge?
proton
electron
neutron
all particles

Explanation:

To determine the subatomic particle with a positive charge, we analyze each option:

• Protons are known to carry a positive electric charge.
• Electrons carry a negative charge.
• Neutrons are electrically neutral (have no charge).
• Not all subatomic particles have a positive charge (e.g., electrons are negative, neutrons are neutral).

So the correct option is the one corresponding to proton.

Answer:

A. proton (assuming the first option is labeled A, with the text "proton")
